Lenovo United States Inc. (Lenovo) is a company that manufactures computers based in Morrisville, North Carolina. Lenovo sold or offered for sale desktop computers, notebook computers and workstations in California, from September 2019 to September 2023.

This case was the result of an investigation performed by California Energy Commission (CEC) staff. CEC’s investigation and testing process identified that Lenovo was manufacturing and offering for sale desktop computers, notebook computers and workstations that did not meet the efficiency standard and were not certified to the Modernized Appliance Efficiency Database System (MAEDbS).

To resolve this matter, Lenovo executed a Settlement Agreement with CEC on March 24, 2025, for $471,000.00. The penalty monies are deposited into the Appliance Efficiency Enforcement Subaccount as required in Public Resources Code 25402.11. Lenovo has also agreed to a compliance plan to test and certify all models to MAEDbS before continuing to sell in California.
